The Bucees chain has E0 fuel pumps these are the mega chain stations with 100+ pumps on site look for the Red signs directing you to E0 it’s 40 cents more per gallon at the Bucees in Melissa t
Texas vs E10 which is what is mandated here in DFW with E15 being 20 cents cheaper than E10 right now at the same pumps.
User manual on my sonata recommends staying away from E10, let alone E15, thanks for info.
